DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] Refer to the instruction manual Figure 1-2 A combined assembled office desk according to one embodiment of the present invention comprises a column tube 2 and a table top 1 evenly distributed in a ring shape with the column tube 2 as the center, one end of the table top 1 is fixedly connected with a connecting ring 9 movably sleeved on the outside of the column tube 2, and an upper supporting ring 8 for supporting the connecting ring 9 is fixedly sleeved on the outside of the column tube 2, wherein the sum of the thicknesses of the plurality of connecting rings 9 is equal to the thickness of the table top 1, and the connecting rings 9 at the ends of the plurality of table tops 1 assembled into an office desk are sequentially distributed from bottom to top, a supporting leg 3 is provided at the bottom of the other end of the table top 1, and a clamping mechanism 4 for quickly plugging and fixing the table top 1 and the supporting leg 3 is provided between the supporting leg 3 and the corresponding table top 1.

[0050] It should be noted that in the process of assembling the office desk, the table board 1 with the connecting ring 9 located at the lowest point on the outside of the table board 1 is first put on the outside of the column tube 2 and overlapped on the top of the upper support ring 8, and then the table boards 1 are installed one by one according to the position of the connecting ring 9 on the outside of the corresponding table board 1, so that multiple connecting rings are stacked together in sequence. At the same time, each leg 3 is quickly installed on the bottom of the corresponding table board 1 using the clamping mechanism 4. The office desk adopts a connection method in which multiple table boards 1 share a column tube 2 for support, which simplifies the installation process. The appearance of the office desk after installation resembles a flower, breaking the square shape of traditional office desks and making the office desk more artistic.

[0051] Specifically, Figure 2-3 , Figure 6-7 and Fig. 9 As shown, the leg 3 is composed of a central ring block and four oblique strips fixed on the outside of the central ring block, so that the leg 3 is in an X-shaped structure, and the support stability is better. The clamping mechanism 4 includes an insert frame 41 fixed on the top of the two oblique strips at the upper end of the central ring block and a slot 42 opened at the bottom of the table top 1 and corresponding to the insert frame 41. The insert frame 41 is movably inserted into the corresponding slot 42;

[0052] Card slots are provided on both sides of the inner cavity of the slot 42, and straight through slots corresponding to the card slots are provided on both sides of the insertion frame 41. Wedge blocks 43 are inserted into the two straight through slots in a through-type movable manner. The outer sides of the two wedge blocks 43 located inside the insertion frame 41 are fixedly sleeved with a stop frame 44. A spring 45 is fixedly connected between the opposite sides of the two stop frames 44 and the inner side of the insertion frame 41. A top block 46 is provided between the two wedge blocks 43. When the spring 45 is in a natural state, the opposite ends of the two wedge blocks 43 are just completely The two wedge blocks 43 are retracted to the corresponding straight-through groove on the insertion frame 41. At this time, the vertical surfaces of the two wedge blocks 43 at the opposite ends are in contact with each other, and the upper end of the top block 46 is located in the V-shaped groove surrounded by the inclined surfaces of the two wedge blocks 43 at the opposite ends. In addition, notches 47 are provided at the positions of the top blocks 46 at the bottom ends of the two baffle frames 44, wherein the width of the notches 47 is greater than the thickness of the top blocks 46, so that when the two wedge blocks 43 move toward each other under the action of the spring 1 45 at the corresponding position, the top block 46 will not hinder the movement of the baffle frame 44.

[0053] A sliding groove 48 is provided on the inner side of the center ring block, which connects the center ring block and the two oblique bars at the upper end of the center ring block. A top column 49 is movably inserted in the sliding groove 48, and a top ball 410 is fixedly connected to the top of the top column 49. A through groove connected to the inner cavity of the insertion frame 41 is provided at the top of the sliding groove 48. The bottom end of the top block 46 passes through the through groove and overlaps the top ball 410. In the process of the top block 46 moving up and down under the push of the top ball 410, the top block 46 always remains in a state of passing through the inside of the through groove.

[0054] The clamping mechanism 4 also includes two straight bars 411 fixed to the middle of the inner side of the center ring block, a column block 412 is rotatably mounted between the two straight bars 411, and an arc-shaped protrusion 413 is fixedly mounted on the outer side of the column block 412, wherein, when the arc-shaped protrusion 413 and the bottom ends of the two top columns 49 are in a completely separated state (i.e., the bottom ends of the top columns 49 are in contact with the outer sides of the column blocks 412), the opposite ends of the two wedge blocks 43 are completely retracted to the corresponding straight through grooves on the insertion frame 41 under the action of the spring 1 45, and a cross plate 414 for driving the column block 412 to rotate is mounted on the outer side of one of the straight bars 411;

[0055] A through hole is provided in the middle of the bottom of the center ring block, and a plug column 415 is movably inserted inside the through hole. A plug hole is provided on the outside of the column block 412, and a pull ring 416 is fixedly connected to the bottom end of the plug column 415, and a spring 417 417 is sleeved on the outside of the plug column 415 for fixing the center ring block and the pull ring 416. When the top end of the plug column 415 is fully inserted into the plug hole, the spring 417 is still in a stretched state.

[0056] It should be noted that when assembling and fixing the leg 3 to the corresponding table board 1, first pull the pull ring 416 downward to completely disengage the plug post 415 from the socket, and rotate the cross plate 414 to drive the column block 412 to rotate synchronously, so that the arc-shaped protrusion 413 and the bottom ends of the two top columns 49 are in a completely non-contact state. At this time, the top of the plug post 415 is separated from the socket outside the column block 412, and then the plug frame 41 at the top of the leg 3 is plugged into the corresponding slot 42 at the bottom of the table board 1. After the insertion frame 41 is completely inserted into the corresponding slot 42, the cross plate 414 is screwed again to make the arc-shaped protrusion 413 on the outside of the column block 412 contact the bottom ends of the two top columns 49, and the two top columns 49 are lifted to the highest position. At this time, the insertion hole on the outside of the column block 412 is exactly arranged vertically in line with the insertion column 415. The insertion column 415 is inserted into the insertion hole under the action of the second spring 417, so that the position of the column block 412 can be limited;

[0057] When the top column 49 is lifted by the arc-shaped protrusion 413 rotating with the column block 412, the top ball 410 at the top of the top column 49 will move upward synchronously and push the top block 46 to move upward. During this time, the top block 46 moving upward will gradually squeeze the two wedge blocks 43, causing the two wedge blocks 43 to move away from each other, and at the same time compress the spring 1 45 at the corresponding position, so that the opposite ends of the two wedge blocks 43 are respectively inserted into the corresponding card slots;

[0058] The design of the fixing mechanism 4 can quickly complete the installation and fixation between the supporting legs 3 and the table top 1 without the aid of external auxiliary tools, and the connection stability is good.

[0059] Specifically, Figure 2 , Figure 8 and Figure 10-11 As shown, a shelf 7 is provided at one end of the top of the table top 1 close to the column 2 to prevent the assembled table top 1 from shifting. The shelf 7 includes a frame 71, a T-block 12 is fixedly provided at the middle of the outer side of the frame 71, and a square column 13 is fixedly provided at the bottom of the frame 71. A square groove 14 is provided at the top of the table top 1 corresponding to the square column 13, and a T-slot 11 is provided at the top of the outer side of the column 2 corresponding to the T-block 12. The square column 13 and the T-block 12 are movably plugged into the corresponding square groove 14 and the T-slot 11, respectively. A mounting plate 16 for blocking the upper port of the T-slot 11 is fixedly installed at the top of the column 2 by a locking bolt.

[0060] A vertical partition 72 is fixedly provided in the middle of the inner side of the frame 71, and the vertical partition 72 divides the inner cavity of the frame 71 into two storage cavities, and two parallel horizontal partitions 73 are fixedly provided inside one of the storage cavities, which can divide the storage cavity into multiple layers of space for placing office documents. A sink is provided at the top of the frame 71 for placing bonsai or personal items.

[0061] It should be noted that in the process of assembling the office desk, after the installation and fixation of the table top 1 and the legs 3 are completed, and the ends of multiple table tops 1 are sleeved on the outside of the column tube 2, the upper support ring 8 is used to support the stacked multiple connecting rings 9. At the same time, the table top 1 is adjusted to be centered with respect to the corresponding T-slot 11, and then the T-block 12 on the outside of the frame 71 is inserted along the corresponding T-slot 11, and the square column 13 at the bottom of the frame 71 is inserted into the square groove 14 at the top of the corresponding table top 1. Finally, the mounting plate 16 is fixed to the top of the column tube 2 with the locking bolts to block the upper end of the T-slot 11 to prevent the T-block 12 from sliding along the corresponding T-slot 11 and causing the square column 13 to disengage from the square groove 14, thereby causing the table top 1 to rotate around the column tube 2.

[0062] Specifically, Figure 8 and Fig.10 As shown, an air supply pipe 15 connected to the inner cavity of the column 2 is fixedly installed on the top of the mounting plate 16, and an upper exhaust port 17 and a lower exhaust port 18 are respectively opened at the top and bottom of the outer side of the column 2. There are two upper exhaust ports 17 located between each two adjacent T-slots 11 on the outer side of the column 2;

[0063] The two upper exhaust ports 17 arranged adjacent to the T-slot 11 are respectively opposite to the two cavities separated by the vertical partitions 72 on the inner side of the corresponding frame 71, and the inner sides of the two cavities on the frame 71 are provided with connecting ports 20 which are conductive with the corresponding upper exhaust ports 17. A shutter 19 for controlling the exhaust volume and exhaust direction is fixedly installed at a position between the two horizontal partitions 73 inside the frame 71.

[0064] It should be noted that in actual use, the connection lines of computers and host computers of multiple office positions can be routed from the inside of the column tube 2, and are not routed from the connecting port 20 inside the storage cavity where the transverse partition 73 is not installed, which solves the problem of messy wiring on the ground of multiple workstations, so that there will be no accidental contact with the wiring, which may cause unnecessary situations, such as the computer suddenly shutting down when working or when the office documents are not saved;

[0065] In addition, cooling air or heating air can be supplied through the air supply pipe 15, so that air can be discharged from both the upper and lower areas of the table 1 to provide a comfortable working environment. Since air can be discharged from both the upper and lower areas of the table 1 at each workstation, the cooling or heating speed is fast, and uneven cooling or heating of different workstations in the same working environment will not occur.

[0066] Based on the air source for supplying cooling or heating air, a dedicated air supply pipe can be used, or a wind collecting hood can be installed at the air inlet end of the air supply pipe 15, which collects the air blown out by the air outlet equipment (such as a ceiling air conditioner) and then supplies it to each workstation for use.

The positions of the outer sides of the two circular plates 59 corresponding to the limiting grooves 511 are fixed with limiting blocks 510, the limiting block 510 is slidably connected to the corresponding limiting groove 511, that is, the L-shaped column 1 53 and the L-shaped column 2 54 can move away from or towards each other in the area of ​​the columnar groove, which is convenient for adjusting the distance between the L-shaped seat plate 55 and the table plate 1 according to the needs of office workers. In addition, due to the arrangement of the circular plate 59, the limiting groove 511 and the limiting block 510, the problem of the L-shaped seat plate 55 flipping sideways with the L-shaped column 2 54 during use can be avoided, and the stability of use is good.

[0071] It should be noted that, in actual use, when entering the office area to work, the office staff can pull out the L-shaped seat plate 55 from the arc groove 56 by buckling the buckle groove, and pull the L-shaped seat plate 55 according to their own use needs to adjust the distance between the L-shaped seat plate 55 and the table plate 1. If it is necessary to discuss with the neighbor during the office process, the office staff only needs to adjust the direction of the L-shaped seat plate 55 according to the twisting of the body in the sitting state. At the same time, the relative distance between the L-shaped column 1 53 and the L-shaped column 2 54 in the columnar groove area can be further adjusted. Moreover, when it is necessary to use a computer to read materials during the discussion, the office staff only needs to adjust the direction of the computer at the discussion station, which solves the problem of needing to get up and move the chair when discussing at a traditional office desk, and facilitates the discussion.

[0072] On the contrary, after finishing work, when leaving the workstation, the office worker can push the L-shaped seat plate 55 to make the L-shaped column 1 53 and the L-shaped column 2 54 move toward each other, and then move the L-shaped seat plate 55 to store it along the arc groove 56 to the bottom of the table top 1;

[0073] The design of the tilting seat assembly 5 breaks through the traditional design of completely separating the office desk and the seat, and there will be no partial protrusion of the seat after it is stored, and the structural design is novel.

[0074] Specifically, Figure 12-13As shown, a plurality of groups of equally spaced foot assemblies 10 are provided at the bottom of the base 57, and the foot assemblies 10 include a bracket 101 fixed to the bottom of the base 57 by locking bolts, so as to facilitate the replacement of the foot assemblies 10 during later maintenance. A square through groove and an annular through groove are respectively penetrated through the middle and both ends of the bracket 101, and a roller 102 is rotatably installed inside the square through groove, and balls 103 are rotatably embedded inside the two annular through grooves. Straight scraping strips 104 are fixedly provided on both sides of the inner cavity of the square through groove, and annular scraping strips 105 are sleeved on the outer sides of the two balls 103, wherein, during the rotation of the rollers 102 and the balls 103, their outer sides always keep in contact with the bottom end surface of the base 57, and at the same time, the inner sides of the straight scraping strips 104 and the annular scraping strips 105 always keep in contact with the outer sides of the corresponding rollers 102 and the balls 103, and an L-shaped connecting rod 106 is fixedly connected between the outer side of the annular scraping strips 105 and the bottom end surface of the bracket 101.

[0075] It should be noted that, in actual use, the foot assembly 10 can be used to support the base 57. In the process of using the foot assembly 10 to support the base 57, when moving the L-shaped seat plate 55, the rotation of the roller 102 and the ball 103 can be used to reduce the resistance encountered by the base 57 during the movement along the columnar groove direction. At the same time, the rotation of the ball 103 can also be used to reduce the resistance encountered by the base 57 during the deflection process with the vertical section of the L-shaped column 53 as the central axis, thereby avoiding the noise and wear generated by the base 57 sliding relative to the ground in the absence of the foot assembly 10. In addition, during the rotation of the roller 102 and the ball 103, the corresponding straight scraper strip 104 and the annular scraper strip 105 can be used to scrape off the particles or other debris adhering to the surface of the roller 102 and the ball 103 to avoid affecting the rotation of the roller 102 and the ball 103.
